If triangles PQR and STU are similar then PQ corresponds to ST and PR corresponds to SU. Therefore, PQ/ST=PR/SU
Considering that, PQ= 7-x, ST= 13-x, PR= x²+5 and SU= x² +20
therefore, (7-x)/(13-x)= (x²+5)/(x²+20)
cross multiplying,
7x² +140-x³+20x =13x²+65-x³-5x
combining the like terms,
6x² +15x -75=0
solving for x,
x = 5/2 or -5

You are not giving enough information but in one of the calsses the average of student's height might be greater than the other class beacause one of the two classes needs to have 1 extra person than the other calss
Hey there! I'm happy to help!
This number is sixty six thousand six hundred eighty one. This means that our ten thousandths place is the first 6.
We look to the right place to see if it is 5 or bigger. It is also six.
Therefore we bump the ten thousands place up 1 to 7 and we make everything else 0, giving us 70,000.
Have a wonderful day! :D
